You can be stressed at work but if it is persistent it has really dangerous sideaffects as Dr. Geri Puleo (2014) explains in the video below. She states that Burnout is similar to PTSD. Your concentration levels at work and your ability to cooperate with others is reduced due to being angry and over worked. It also makes you wake up every 2 hrs. (The recovery is astonishing – it takes 2 years)
If you continue in your job with such stress it does lead to cancer.
